ELMER H. BRIDENBAUGH, OF DAYTON, OHIO.

AUTOMATIC PUMP-REGULATOR.

reagire.

To all whom it may concern:

Be it known that I, ELMER H. BmDnN- BAUGH, a citizen of the UnitedStates, residing at Dayton, in the county of Montgomery and State ofOhio, have invented certain new and useful Improvements 1n AutomaticPump-Regulators; and I do de- Clare the following to be a full, clear,and eXact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying dra-wings, and to the lettersand figures of reference marked thereon, which form a part of thisspecification.

This invention relates to new and useful improvements in automatic pumpregulators. y

The object of the invention is to provide a device of the above typethat is simple and durable in construction and efficient in operation.

Other objects are attainable, as will appear from the specification andwhich are particularly pointed out in the claims.

Referring to the accompanying drawings, Figure 1 is a side elevation ofthe invention as applied to a pump of the wind-mill type having myimprovements; Fig. 2 is a vertical longitudinal sectional elevation ofthe regulator; Fig. 3 is a section on the line a a of Fig. 2; and Fig. lis a section on the line o o of Fig. 2.

Throughout the specification and drawings, similar reference charactersindicate corresponding parts. l

'Referring more particularly to the drawings, 1 represents a pumpcylinder provided with a discharge pipe 2, which, in the caseillustrated in the drawings, leads to an underground reservoir 3 intowhich the water is pumped against air compressed therein. The cylinder 1is provided with a piston rod 4 attached to a pump rod 5, which is, inturn, connected to the actuating mechanism of a windmill when the motivepower is of that kind. In the present case the windmill (not shown) ismounted on a frame 6, and the pump may be provided with a lever handle 7and a discharge spout 8, which may be used independently of thewindmill. To enable the wind-mill to be placed out of operation when thedesired quantity of water has been pumped, it may be provided with apull-out cord 9 which is connected to the vane of the mill and which,

when pulled downwardly, will throw the vane to one side, thereby placingthe sails out of the path of the wind which prevents its continuedoperation. As the wind-mill parts are well known and understood, it hasnot been deemed necessary to illustrate them. To enable the cord 9 to bepulled automatically when sufiicient water has been pumped, and which isindicated by the. pressure thereof, the following device is provided.

Attached to the lower end of the pull-out cord 9 is a piston rod 10,which passess through a stufhng boX 11. The said rod 10 is provided witha. piston 12 on its lower end. The piston 12 reciprocates in a cylinder'13 provided with a bracket 14 which may be attached to the dischargepipe 8, and through which the cylinder is supported. The chamber withinthe cylinder 13 above the piston connects with the reservoir 3 throughthe pipe 2, a lateral communicating pipe 15, and a passageway 16. Boththe lateral 15 and the passageway 16 communicate with a chamber 17 in ahousing 18; and within sai-d chamber 17 is a valve 19 parts of whichcoperate with seats 20 and 21 and control the passage of water from thedischarge pipe 2 to the cylinder 13. The said valve is -ioined to aguide cylinder 22 mounted within the housing 18, both parts beingnormally held down by a spring 23 mounted on a yielding stem 24. Thetension of said spring may be regulated by a nut 25. The stem 24 at itslower end engages the upper side of said valve and its upper end entersan aperture in the nut 25. lll/Then the pressure of the water in thedelivery pipe 2 and the lateral 15 becomes sufficient to overcome thetension of the spring 23, the valve portion 19 instantly opens andallows the water to enter the passageway 16 and cylinder 13, therebylowering the piston 12 and cord 9 and thus placing the windmill out ofan operative position. The valve 19 does not completely open until thepiston portion thereof passes the seat 21, which prevents the said valvechattering when said valve opens.

The housing 18 is provided with a seat 26 adapted to be engaged by avalve 27 on the guide cylinder 22 when the valve 19 is opened. When thevalve 27 is in engagement with the seat 26, it prevents the waterescaping around the guide cylinder, thereby insuring the entire pressureof the water in the chamber 17 being exerted against the piston 12. Whenthe pressure of the water in the discharge pipe 2 falls sufficiently toallow the spring to close the valve 19, which pressure is controlled bythe nut 25, the water in the cylinder 13 above the piston escapesthrough a port 28. The port 28 is controlled by a valve 29 in a head 30mounted above the housing 18. The valve 29 is connected to the stem 24by a stem 31; and

-the position of the valve 29 is such that,

when said valve 19 is closed, the valve 29 will be opened, and viceversa. As a consequence, after the valve 19 is opened by the waterpressure, the valve 29 will be closed, which prevents the water escapingthrough the port 28 when the piston is being moved downwardly and isbeing held in a lower position by the water. When the pressure of thewater in the discharge pipe 2 falls to a point that allows the valve 19to close and the valve 29 to open, the piston 12 will be relieved fromthe pressure of the water and can consequently be elevated. Thiselevation may be accomplished by any means, such as the vane of the millitself, which will be thrown into the wind when the pullout cord 9 isreleased as is common with windmills.

The chamber 17 may be provided with a safety valve 32 mounted in alhousing 33 provided with an outlet 34. The valve 32 is controlled by aspring 35, the tension of which may be adjusted by a nut 36. The safetyvalve 32 prevents the water exerting an excessive pressure in thechamber 17 and cylinder 13.

It may be stated that when the tank 3 is nearly full, and the pressurehas dropped slightly below that at which the regulator is set, the valve21 may be closed and the valve 29 opened by pressing on the stem 31,thereby allowing the piston 12 to ascend and the windmill to be placedin operation. The water may therefore be discharged from the pumpwithout passing through the reservoir, which allows a supply to bemaintained. It may be further stated that the area of the valve 19controls, in connection with the spring 23, the point at which the valvewill open, and that the area of the valve 27 controls, in connectionwith the spring 23, the point at which the valve 19 will close. Thedifferential area of the valves 19 and 27 therefore regulates thedifference in pressure between the opening and closing of the valve 19.

Having described my invent-ion, I claim:

1. In a device of the type specified, a pump, a reservoir, a dischargepipe leading from the reservoir to the pump, a cylinder having an outlettherein, a piston within said cylinder, a housing having a chambertherein, said chamber communicating with said cylinder and saidreservoir, a valve mounted in said chamber and controlling thepassageway between the reservoir and the cylinder, a guide cylindermounted in said housing and forming a guide for said valve, a secondvalve mounted in said guide cylinder and adapted to seal the jointbetween the housing and guide cylinder when said first named valve isopened, and a third valve controlling the outlet of the cylinder andactuated by said first named valve.

2. In a pump regulator, the combination with a pump cylinder, areservoir, and a discharge pipe forming a communication between saidpump cylinder and said reservoir, a cylinder 13 having an outlet, and apiston in said cylinder, of a housing 18 forming a chamber whichcommunicates with said cylinder and said reservoir, a valve 19 mountedin said chamber and controlling the communication between the reservoirand said cylinder 13, the valve 19 having an extended portion 22 forminga guide therefor, a spring-controlled stem 24 normally controlling saidvalve and extension, a valve 29-30 mounted above said housing 18, thestem of which is joined to the stem 24., said valve 29-30 being ada-ptedto control the outlet to the cylinder 13, and a valve 26-27 moving inunison with the valve 19 and adapted to seal the joint around the valveextension 22, substantially as herein shown and described.

In testimony whereof I affix my signature, in presence of two witnesses.
